Opis:
This paper addresses the synthesis problem of Jacobian inverse kinematics algorithms for stationary manipulators and mobile robots. Special attention is paid to the design of extended Jacobian algorithms that approximate the Jacobian pseudoinverse algorithm. Two approaches to the approximation problem are developed: one relies on variational calculus, the other is differential geometric. Example designs of the extended Jacobian inverse kinematics algorithm for 3DOF manipulators as well as for the unicycle mobile robot illustrate the theoretical concepts.

Opis:
In a region of two lithologic units: the Augustów Plane sandr and the Suwałki sands and fluvioglacial gravels, 134 measurements of radon concentrations in dwelling houses were performed. An integral method of solid state nuclear trace detectors (SSNTD) was used in the studies. Statistically significant differences in the radon concentrations in both geological units were obtained. The radon concentration arithmetic mean was 197 Bq m-3, geometric mean - 119 Bq m-3, median - 111 Bq m-3, the maximal value being 1225 Bq m-3 in the region of the Suwałki fluvioglacial sands and gravels. The Augustów Plane sandr revealed arithmetic mean of radon concentration equal to 123 Bq m-3, geometric mean – 80 Bq m-3, and median equal to 67 Bq m-3, maximal value 695 Bq m-3. The annual effective dose of the radon obtained by inhabitants of the Augustów Plane sandr is 1.7 mSv and for inhabitants of the Suwałki fluvioglacial sands and gravels it is 2.5 mSv.

Opis:
Multiple sclerosis (MS) is the most common autoimmune disease affecting the central nervous system, characterized by the presence of scattered foci of demyelination in the brain and spinal cord. Magnesium (Mg) has a significant influence on the nervous system and the immune system. The aim of this study was to evaluate the influence of the concentration of Mg in the serum on the ability status of patients with MS. The study group consisted of 101 adults with diagnosed relapsing remitting MS. All participants were investigated on the Expanded Disability Status Scale. The control group included 41 people. The concentration of Mg in the serum was determined by the flame atomic absorption spectrometry method. The patients completed a survey and a 24-hour dietary interview. In patients with MS, the percentage of respondents with normal magnesium content was significantly lower than in the control group (p < 0.05). The study proved that patients with normal Mg serum concentration levels were in better clinical condition, particularly with respect to the function of the pyramidal tract (p = 0.007) and sphincters (p = 0.002), than patients with inadequate levels of Mg in the serum. External factors such as gender, smoking, immunomodulating medications or dietary supplements of Mg were found to have no effect on the concentration of Mg in the serum of MS patients. The results of our study suggest that an abnormal concentration of Mg in the serum of MS patients should be recognized and corrected, as this may improve the health status of people with MS.

Opis:
When faced with a chronic disease such as rheumatoid arthritis, the patient attempts to cope with the stressful situation by applying coping strategies. The main aim of rheumatoid treatment is not only improving health but also increasing the quality of life. The research objective was to determine the relationship among socio-demographic factors, duration of the disease and its associated ailments, attitude to the disease, self-assessment of one’s knowledge of RA, and the application of coping strategies in stressful situations by women with rheumatoid arthritis. The study involved 193 patients of the Clinic of Rheumatology and Systemic Connective Tissue Diseases, and the Rheumatology Unit of the Specialist Outpatient Clinic of the Independent Public Teaching Hospital No. 4 in Lublin, from November 2016 – June 2017. The Coping Orientations to Problems Experienced Inventory (COPE) Questionnaire and an author’s Original Questionnaire were used in the study. Analysis of variance (ANOVA) and Tukey’s range test were applied for statistical analysis. A p-value<0.05 defined the statistical differences. Analysis was performed using the commercial SPSS Statistics 19 software (IBM Corp., Armonk, NY, USA). The respondents usually use instrumental social support (11.5±1.7), focus on and vent emotions (11.4±1.9), use emotional social support (11.4±1.8), employ active coping (11.4±2.1) and positive reinterpretation and growth (11.2±1.8), and least often rely on their sense of humour (5.5±1.4) or use alcohol or drugs (5±1.1). The factors which determine the types of strategy used are age, education, the duration of the disease, ailments experienced, and attitude towards the disease. Those respondents who declared a greater knowledge of RA more often applied positive reinterpretation and growth, and more rarely used alcohol or drugs. In the treatment and rehabilitation processes it is important to reinforce in the patient positive expectations for the treatment, seek advantages and benefits in one’s present health status, and educate patients about the disease, its therapy and appropriate coping strategies.

Opis:
A detailed investigation of current-voltage (I- V)characteristics of semi-insulating GaAs sample was performed in the vicinity of room temperature. The sample with 300 K resistivity of 2 x 10$\text{}^{7}$ Ω cm was supplied with guard-ring electrodes which allowed the elimination of surface currents. The observed characteristics started with an ohmic part which was followed by a superlinear current on voltage dependence. At a threshold voltage V$\text{}_{th}$ which corresponds to the electric field of about 2 kV/cm the current increased abruptly by a few orders of magnitude. The value of V$\text{}_{th}$ increased with the temperature. It is proposed that the observed shape of the I-V curve is caused by the filling of the EL2 level with injected electrons heated by the electric field.

The mechanisms of irregular photoluminescence intensity oscillations, as observed in optically detected cyclotron resonance experiments, are discussed. Two possible scenarios are analyzed, both requiring impact ionization of the center(s) by electric field accelerated free carriers. The first assumes coexistence of dielectric and energy relaxation processes. The second assumes a subsequent impact ionization of two different centers.

Opis:
Six radon laboratories, which perform indoor radon measurements to jointly investigate temporal variations of radon concentration in houses in a couple of regions in Poland, participated in the intercomparison exercise. There are involved three commercially available Hungarian RadoSys systems and four own laboratory methods. All of them are based on the etched-track CR-39 detectors. The intercomparison was conducted in a calibration laboratory of the Central Laboratory for Radiological Protection (CLOR), Warsaw, Poland, accredited by the Polish Center for Accreditation (previously AP 101, at present AP 057). Comparison measurements were performed during three expositions in the CLOR’s radon calibration chamber under controlled normal climatic conditions and steady radon concentration. The results were referred to the value of the radon concentration determined by AlphaGUARD monitor traceable to the primary 222Rn standard in Physikalisch-Technische Bundesanstalt (PTB), Braunchweig, Germany. The mean performance ratio defined as a ratio of the reference to participant’s result range from 0.88 to 1.31.

Opis:
PicoRad system based on activated charcoal collectors and liquid scintillation counter is one of the most popular passive methods of radon measurements which may be used both indoors and in other environments such as caves, tunnels, mines etc. It is well known that charcoal is also a very good adsorber of water vapor and it can reduce adsorption efficiency for radon. In PicoRad collectors, the charcoal is mixed with a dessicant to lower this effect. A series of expositions of PicoRad detectors was performed in a Central Laboratory for Radiological Protection (CLOR) radon calibration/climatic chamber to study the effect of high relative humidity on the airborne radon concentration measurements and the dependence of the results on the duration of exposure. The results obtained from the PicoRad system were referred to the mean concentrations delivered by an AlphaGUARD monitor, Genitron (GmbH), Germany. The main conclusions are the following: 1) the PicoRad system results are not affected by high relative humidity, including extreme values of 90-96%, for the duration of exposure up to ca. 24 h; 2) in the relative humidity range of 75-96% the correction coefficient linearly depends on the duration of exposure reaching a value of ca. 16 for 96 h exposure; 3) the PicoRad system delivers results corresponding better to the mean value of radon concentration in the last 6 h interval of exposure than that in the whole exposure duration. This finding is particularly important for the calibration of PicoRad collectors in the conditions of decreasing radon concentration due to radon decay.

Opis:
Malaria remains a major health issue In the world, while in Poland no cases of the indigenous disease have been observed since 60-ties of the last century, but the number of cases imported from the epidemic areas is increasing. The aim of work was to analyse the epidemiology of malaria diagnosed and treated in the Department of Infectious Diseases and Hepatology, Pomeranian Medical University, Szczecin, Poland from 1.02.2010 until 31.01.2011. In total 11 cases were found, all diagnoses based on the thick and thin blood smear microscopy, alongside to the standard laboratory analyses.All clinical data presented are based on the case history. Results: Majoriry of cases reported travel to Sub-Saharan Africa (45%) or Indian subcontinent (27%). The travel was usually for recreational purposes, with significant proportion (45%) of patient not taking the malaria prophylaxis. Clinical course of infections was largely mild, with dominance of Pl. Falciparum parasitaemia. Fever was the most common clinical symptom (90%), while in the routine laboratory test no significant abnormalities, suggesting the disease, were found. Conclusions: malaria should be suspected in every case of the returning traveler with fever, especially if the travel was to the endemic area. The exclusion of the disease cannot be based on routine laboratory tests or quick immunoassays – thick and thin blood smear microscopy must be performed.
Malaria ciągle jest głównym problemem zdrowotnym świata, natomiast w Polsce od lat 60. ubiegłego wieku nie stwierdzono rodzimych przypadków malarii. Zwraca jednak uwagę ostatnio rosnąca liczba pacjentów z malarią powracających ze stref epidemicznych. Celem pracy była analiza epidemiologiczna wszystkich przypadków potwierdzonej malarii leczonych w Katedrze i Klinice Chorób Zakaźnych PUM w Szczecinie w okresie między 1.02.2010 a 31.01.2011 r. Do analizy zakwalifikowano 11 przypadków malarii hospitalizowanych w Oddziale Chorób Zakaźnych i Hepatologii. U wszystkich rozpoznanie tej parazytozy oparto na badaniu grubej kropli i cienkiego rozmazu, dodatkowo u wszystkich wykonano rutynową diagnostykę laboratoryjną. Dodatkowe informacje uzyskano na podstawie poszerzonego wywiadu lekarskiego. Wyniki: najczęściej pacjenci z malarią powracali z Afryki Subsaharyjskiej (45%) bądź z Półwyspu Indyjskiego (27%). Większość osób wyjeżdżała w celach turystycznych, a znamienna większość nie przyjmowała chemoprofilaktyki przeciwmalarycznej. Wśród analizowanych pacjentów, poza jednym przypadkiem, dominowały łagodne postaci malarii, głównie gatunek Pl. falciparum. Prawie u wszystkich osób występowała gorączka (90%), natomiast w rutynowych badaniach dodatkowych nie wykazano odchyleń uznanych za wykładniki tej choroby. Wnioski: malarię należy podejrzewać u każdego chorego powracającego z rejonu epidemicznego, zwłaszcza, jeżeli występuje gorączka. Nie można wykluczyć tej choroby na badaniach rutynowych czy szybkich testach immunoenzymatycznych, a jedynie na podstawie grubej kropli i cienkiego rozmazu.

Opis:
4BrABT (2-(4-Bromophenylamino)-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazole) is a compound known for its interesting in vitro anticancer profile. 4BrABT inhibited proliferation and motility of several cancer cell lines in concentrations which were not toxic to normal cells. A major problem associated with cancer chemotherapy, but also caused by environmental factors such as pesticides, is neurotoxicity. Therefore, the aim of the presented study was an in vitro evaluation of the neuroprotective activity of this compound. 4BrABT activity (1–100 μM) was tested in cultures of mouse neurons, rat astrocytes and rat oligodendrocytes. A possible protective action of the compound in different neurodegenerative models, as serum deprivation (SD), excitotoxicity (presence of 500 μM glutamate in culture medium), as well as cisplatin toxicity (astroglia – 50 μM and oligodendroglia – 100 μM) was investigated. Cell viability in the tested cultures was assessed with the use of LDH and MTT methods. Moreover, 4BrABT ability to prevent the cisplatin-induced apoptosis in astrocyte and oligodendrocyte cultures was analysed after Hoechst 33342 fluorostaining. The obtained results indicate that 4BrABT was not toxic to neurons, astrocytes and oligodendrocytes. Moreover, a decrease in the neuronal LDH level was observed, which may suggest the ability of 4BrABT to act as a trophic agent. Furthermore, the protective action of the studied compound was shown in neuronal cultures exposed to neurotoxic conditions (presence of glutamate and trophic stress) and in cisplatin-treated astrocytes and oligodendrocytes. The expression of anticancer and neuroprotective activity raises hopes for the potential use of 4BrABT as a safe anticancer drug, or neuroprotective agent in chemotherapy-associated neurotoxicity.
